Hello everyone,
I am using the STM32F303VC, trying to interface to a SPI EEPROM over DMA and having some issues on the reception of the data. The DMA is set up as full duplex, and I can see the transmissions...

Hello,
I'm trying to trigger an ADC conversion externally from TRGO2 and store it to a buffer through DMA. However, it doesn't appear that anything is being written to that buffer. Could someone please look...

Hello everyone, I'm new to STM32 microcontrollers. I'm currently working on my first project using this microcontroller, it is for a motor control application. I am trying to set up the PWMs, I'd like to run t...
Posted on January 18, 2018 at 14:46Thanks for the replies!It seems that the issue was resolved after adding the RX FIFO threshold to quarter full:SPI_RxFIFOThresholdConfig(EEPROM_SPI,SPI_RxFIFOThreshold_QF);Makes sense since I'm doing byte-wide tran...
Posted on November 17, 2017 at 21:17 I appear to have solved the issue. Looking further in the datasheet I realized that ADC2 was not connected to DMA1 channel 1 The correct DMA connection to ADC2 is DMA2 Channel 1:
Posted on November 16, 2017 at 17:23Certainly. Thanks for your help so far!Here's the register content:ADC2 CR: 0x10000005ADC2 CFGR: 0x00000683DMA1_CH1 CCR: 0x000025A3DMA1_CH1 CNDTR: 0x00000002DMA1_CH1 CPAR: 0x50000140DMA1_CH1 CMAR: 0x2000001C
Posted on November 16, 2017 at 16:13You mean by calling /* Configures the ADC DMA */ ADC_DMAConfig(ADC2, ADC_DMAMode_Circular); /* Enable the ADC DMA */ ADC_DMACmd(ADC2, ENABLE);?I did that and removed the ADC interrupt, instead added the DMA interr...
